Which item is commonly documented in NFPA 13E maintenance records to track water supply?

• A. Architectural room numbers
• B. Water supply notes
• C. Employee birthdays
• D. Retail inventory numbers

Answer: (B)

Tracking the water supply is a central element of maintenance documentation under NFPA 13E. The maintenance records routinely include water supply notes that capture pump status, pressures (static and residual), flow conditions, and the condition of water sources such as storage tanks or external supply mains. Recording these details helps verify there is enough water available to meet the system’s demand during a sprinkler activation and makes it easier to spot trends or deficiencies over time. The other options don’t relate to water supply tracking: architectural room numbers are about layout, employee birthdays are unrelated to system performance, and retail inventory numbers have no connection to fire protection water supply.
